What to price my 36 lesco wb for

I have a late 90s early 2000 Lesco wb 36 belt driven, It has a Kawasaki fc420v motor . Put new ignition coil on , oil change and new spark plug, Blades are decent and mower is in great shape. But just can not seem to find a comfortable price to sell. dont wanna give it away but would like to sell it. any ideas on price. heres a pic

I purchased the identical mower a few years back for $700...condition was similar to what yours appears to be in. I knew the guy so he gave me a deal. I wouldn't sell it less than $650 but that's me, no more than $800
